Hmmmm Low Delta T?????????

Now, I'm sure that's the wrong answer so feel free to berate me and inform me of my shortcomings...maybe we will all learn something.

Mike I don't berate anyone just trying to draw old BK out on his Delta T and he just clammed up

You were right in your assumptions if left running long enough in my example that unit would have drawn the house down to the low 70's

Excellent..I suspected there was something with your example that would have demonstrated the inadequacy of using a delta T to judge a system but I guess not. I do wish there was a better way, short of gauges.

Ah your temp gun out of calibration or the blower was connected to the meat freezer

You know...that's exactly what I thought..a low battery maybe. I replaced the battery and double checked the gun outside and at several other locations where the temperature was predictable. Didn't seem to be the gun but I couldn't believe what I was seeing. Turned out the two filters were completely clogged and obstructing the air flow over the coil. I removed the dirty filters and the delta-T came to 19 degrees in about 5 minutes. I still can't believe the 26 degrees reading though .
